Cover Story: Antimicrobial resistance is presently one of the leading causes of death worldwide. Surveillance of different environments, including wastewater treatment plants (WWTPs), recognized as hotspots of antibiotic-resistant bacteria, has become crucial within the One Health approach. This study characterized antibiotic-resistant bacteria in a WWTP. Resistance to tetracycline (32.5%) and ampicillin (25%) was the most common phenotype among the 50 isolates. Three strains belonging to the genera Citrobacter, Shigella and Klebsiella exhibited multidrug resistance. Additionally, four antibiotic resistance genes and class 1 integrons were identified. This study highlights the WWTP’s role as a reservoir/source of antibiotic-resistant bacteria/genes in the environment, underscoring the need for heightened surveillance and containment measures.
